Wireless mouse runs without a battery or battery charging


Sanwa Supply is selling a wireless mouse, 400-MA052, for ¥2,980. It runs without a battery or battery charging. It is powered wirelessly from the accompanying mouse pad.

Once you connect the mouse pad to a USB port, it starts producing a magnetic field, powering the wireless mouse’s circuit.

Wireless mouse: W67 x H37 x L105mm, 72g
Mouse pad: W105 x H215 x L15mm, 140g / Cable length: 1.4m

    But why wouldn't a person just but a wired mouse? because one still has to plug in the mouse pad

    Mouse pad? Now that's a name I haven't heard in a long time. A long time.

    the point of a wireless mouse is that you don't have as many cords over your desk - so this failure defeats that purpose

    I use a Logitech track ball bluetooth mouse with four buttons and a scroll wheel. The batteries last more than 2 years. But the cost is about the double of this one.

    I've seen these on sale a decade ago, when battery life on wireless mice was still an issue.

    LOL Epic Fail. They just moved the wire from the mouse to the mouse pad. You're STILL tying up a USB port, and the mouse becomes useless once the mouse pad breaks. At least with a battery-operated bluetooth mouse you are TRULY "wireless" and there's no cable getting in the way.
